Show Notes #102
Episode #102 Audio (Listen Now):
Introduction:
- Rob from the MintCast podcast is on the show tonight filling in for the nomadic and enigmatic Richard.
Announcements:
- The 2013 Dayton Hamvention is coming up May 17-19 in Dayton, Ohio. We are still in need of donations. Please keep ‘em coming.
- The Wouff Hong Podcast, member of the Black Sparrow Media Network, have released their first episode. If you don’t subscribe to the BSM aggregate feed, you can find them at the link above. Good episode, and they mention LHS.
- Rob and Russ use BeyondPod on Android as a podcast manager.
- Roy, KK4ATD, will be in Atlanta at RARSfest as an ambassador for LHS. If you’re anywhere near Raleigh, NC on Saturday, March 30, 2013, stop by and say hello. [LHS will NOT be present at RARSfest this year. Sorry for any confusion. -Ed]
- The sponsored ads in the right column of the LHS web site actually make us a not insignificant amount of money when you click on them. If you want to help us out without donating your own money, please click on an ad when you visit our site. We get money in our donation box, and you don’t lighten your own pockets. Thank you!
Topics:
- Visit KE8P’s blog. One of the articles documents using a Raspberry Pi as a temperature monitor.
- KK4ATD has developed Hamux, a 64-bit, CentOS-based Linux distribution with ham radio applications. This is a “live” CD image, so you can boot it from CD and try it before installing. At 698MB, it just barely fits on a CD.
- Our hosts embark on a brief digression about Douglas Adams.
- Slow Scan TV (SSTV)SSTV is a method of sending still images using radio frequencies on the HF bands. FSTV (fast-scan TV), which is typically done on VHF and UHF frequencies at distances up to a couple hundred miles, is similar to broadcast TV.In order to operate SSTV, you’ll need a radio (and a license to transmit), a computer, a sound card interface to connect them to each other, and software. For Linux, we have QSSTV. The current version is 7.1.7, released on January 4, 2012. It is compatible with the Ham Radio Control Libraries (hamlib) for controlling the radio.Russ gives a brief overview of the various configuration options and interface of QSSTV.
- Rob is not a ham, but has considered obtaining his license. Unfortunately, he lives in an area with deed restrictions that prohibit outside antennas. What are his options? There are several resources on the web for ham operation with antenna restrictions. Some of these are:
- http://www.stealthamateur.com/
- http://www.g4ilo.com/stealth.html
- http://www.iw5edi.com/ham-radio/?attic-antennas,131
Though in Rob’s case, with aluminum foil-lined roof tiles, attic antennas are not likely to work very well.
Other possibilities: using EchoLink, IRLP, operating mobile or portable. Perhaps tossing up a temporary wire antenna in the back yard, operate, then take it down.
Rob and Russ discuss the various options, potential for TVI, and VEC testing opportunities.
Feedback:
- David, KE0AZ, writes to say he’s sorry to see Richard to go, but will continue to listen.
- Frank, K4FMH, would like to see more technical content in future episodes.

LHS Episode #102: Run, It’s George Lucas!
Here we are, two episodes past the Richardocalypse and the calendar hasn’t run out yet! This time around, I’d like to thank Rob from MintCast for once again stepping in to be a co-host on the show, filling in the left big toe of the shoes once worn by The Richard himself. Since I barely fill a pinky toe, myself, that’s really saying something. In this episode we go a little ham nutty with Linux thrown in. Topics range from slow-scan television to licensing requirements to Rob asking, “What do I need another damned hobby for??” That question and many others answered in this fabulous installment of Linux in the Ham Shack.

Show Notes #101
Introduction:
- Russ flies solo on LHS! Well, almost. Harrison, VE2HKW, fills in as co-host.
Topics:
- What’s in a name? Russ talks about the philosophical ramifications of the phrase “Linux distribution”, and referring to Linux vs. GNU/Linux. Richard Stallman prefers using GNU/Linux to refer to the operating system, and Russ seems to agree, but feels it doesn’t go far enough. Share your thoughts via the usual communication channels.
- hamqth.com is an alternative to QRZ.com for callsign lookups, and has an application program interface (API). Russ has programmed the gnorman bot in the LHS IRC channel to access hamqth.com. While in the chat, enter “.qrz some_callsign”, and gnorman will return the info.
- Another application that uses the hamqth.com API is QtLog. It’s mostly in German, but there’s enough English to allow you to use the program. It seems to require that you have a MySQL server running on the same computer. It also supports HamLib for rig control. You can use Google Translate to translate the website.
- Harrison offers an overview of oscilloscopes, including what they are, the controls, and how you might use one in your ham shack. There are several instructional videos available on W2AEW’s YouTube channel. (You can learn more about Alan, W2AEW, on his QSL.net page. There are also software-based oscilloscopes, like xoscope. Of course, you’ll need a hardware interface to the computer’s sound card.

LHS Episode #101: O Sole Mio
Welcome to the first episode of Linux in the Ham Shack that doesn’t have Richard it in, on purpose. I can personally say that I feel his absence rather heavily in this program, but overall I think the show went rather well. Harrison, VE2HKW, was kind enough to be a guest host to help me out. Episode #102 will also have a couple of guest hosts, rather likeable ones at that, and so it will go until a permanent(?) replacement is found for Richard. We can only hope he comes back one day to grace us with tales of strippers on scooters and discharging firearms indoors. Until then, I soldier on. Thanks for listening and remember, you can send feedback to [email protected], or by voice mail at 1-909-LHS-SHOW (547-7469).

Don’t Fear the Penguin
It’s day four of my hopefully last Windows-to-Linux migration, and so far so good. I have my HRD log imported into CQRLog and it’s talking to both my Arduino Keyer and Yaesu FT-897. The Keyer is happily sending CW and CQLog is reading the rig frequency. The rig control function is very simple and utilitarian compared to HRD’s, but it works. What I cannot get working is controlling the Kenwood TS-850. This appears to be a problem with Hamlib, which CQRLog uses via rigctld.
I found that Linux re-enumerates USB /dev/ devices if you unplug one. For example, I had my Arduino Keyer at /dev/ttyUSB0, my TS-850 interface at /dev/ttyUSB1, and my FT-897 interface at /dev/ttyUSB2. Upon unplugging the Arduino Keyer and TS-850 interface, the FT-897 became /dev/ttyUSB0, and with nary a mention in syslog. I find this behavior strange. But I’m really pleased Linux handles USB device insertions and ejections so well. Back in the day to do stuff like this you’d have to edit some text file, recompile your kernel, and walk uphill in snow both ways.
To run N1MM I installed Virtualbox and within that installed a very bare bones Windows XP installation. This enables me to run Windows XP as a virtual machine within Linux, without rebooting. N1MM installed and ran without a hitch in the virtual machine. I was reminded N1MM likes to install in C: root, like it’s 1994 on Windows 3.1. But I digress. Attaching host USB devices to virtual machines in Virtualbox is a piece of cake and I had N1MM talking with the 850. So I’ve got my contesting needs covered.
It occurred to me that it wouldn’t take much to get CQRlog to do basic contest logging. It already has cw interface keying and function key definitions and macros. All it really needs is serial number generation with corresponding function key macros, previous QSO report lookup, and perhaps a little more field customization. This would cover the basics. One can handle scoring outside the program, but a band map with the DX cluster integrated would be the next feature on the list. I may just look at the source code and see if I can make sense of it and maybe play around with some customizations. I sense another project I’m going to get sucked into.
So far I haven’t had to go back to my native Windows installation for anything, other than to steal more disk partition space. Maybe I cheated a little by installing an instance of Windows XP on Virtualbox, but hey, whatever gets the job done!
(Update: I just found the CQRLog band map window and it is integrated with the DX cluster!)
Migrating to Linux (Again)
I’m no stranger to Linux. I’ve run numerous distributions since about 1995, even venturing into BSD territory, running FreeBSD and some other Berkeley variants. I’ve also used Linux quite a bit in my professional life for servers. However, I’ve never made the jump to using it as my primary desktop operating system at home; it’s always been a novelty to play with and never a desktop workhorse that I would use to actually get things done.
Linux Mint is a Linux distribution that has become more popular recently. It’s based on the venerable Ubuntu distribution and appears to be taking some market share from Ubuntu. Ubuntu in my opinion went off the tracks with its migration to the Unity desktop. For the first time recently I hit a brick wall trying to install the latest Ubuntu within a virtual machine. While Ubuntu was quite polished and arguably had the best usability in the Linux world, I still felt that I was often fighting the operating system to make it work.
Linux Mint seems to have taken care of those issues. Last night I made the plunge and partitioned off some space on my hard disk and installed it so I could dual boot between Windows and Linux. The installation went extremely well and within two hours I was able to browse the web, play videos and hear sound, send email, work on Kicad schematics, compile Arduino code, open Excel and Word docs, do my banking with the same program I used on Windows, and I had amateur radio logging and digital programs installed. The only speed bump was getting my wireless working. I was able to fix that in five minutes after Googling and finding one command line to run. On previous distributions, items like this would take hours to resolve and there would be several of them to deal with. For the first time I feel I have something equivalent to what I had on Windows, and it doesn’t look goofy and didn’t require days of tweaking with arcane command line syntax to make it acceptable. The browser actually renders things like they look on Windows. You install a program and it actually appears in the menu. Quite simply, Linux Mint isn’t a compromise like previous desktop installations.
I’ve often complained about the state of amateur radio open source software. I stand by my previous statements as I think we still don’t have a suite of amateur radio open source software that compares with offerings in Windows, mainly in the areas of logging and contest programs. However, CQRLog has evolved quite a bit and I’ve decided to take a more minimalist approach and see if I can make it work. I still think Ham Radio Deluxe is the gold standard, but lately I’ve become annoyed with its bloat and the commercialization and marketing of it.
I’m still keeping my Windows partition, mainly to run one particular contest program and store my documents (which I access from Linux), but I may eventually run Virtual Box on Linux and have a small Windows installation virtualized to run the contest program rather than booting back into Linux.
Will this be the time I finally run my shack on Linux? I hope.
